The invention shall now be explained in greater detail, together with the figures related below, merely as an example, which follow this report as an integral part, and in which:
The pneumatic controller (2) includes a terminal module (2A) and a number of extension modules (2B). The number of extension modules (2B) varies with the size and geometry of the tank (8) to be inspected, whose mould is defined by a dedicated computer program to allow the movements of the system be properly coordinated. Therefore, the number of extension modules (2B), presented in
The connecting cables (7a, 7b e 7c) have the function to allow the transmission of analogue or digital signals between the pneumatic module (3), the interface module (4), the control module (5), and the operation module (6).
In this way, modules (4, 5, 6) may form one single component, for example, a computer with proper output plates linked by a cable to the module (3).

As mentioned above, the pneumatic controller (2) includes a number of extension module (2B) and a terminal module (2A), connected to each other. The configuration of the pneumatic controller (2) should be defined as a function of the geometry of the tank (8) to be inspected. If the tank is small, the pneumatic controller (2) may be the terminal module (2A) itself.
Once connected, the extension modules (2B) and the terminal module (2A) become one single component, or in other words, the pneumatic controller (2). The pneumatic controller (2) will receive gas in each of pneumatic chambers of terminal module (21) and pneumatic chambers of extension module (31), individually, which will allow a variation of its form and its position within the tank (8). The calculation of the pressure that must be maintained inside each pneumatic chamber of terminal module (21) and each pneumatic chamber of extension module (31), for the definition of the position of the pneumatic controller (2), is made by the control module (5), through a specific computer program for this function. It should be mentioned that the clad tube of terminal module (20) and the clad tube of extension module (30) must be flexible enough to allow the pneumatic controller (2) be deformed. The central tube of the terminal module (25) and the central tube of the extension module (35) give a minimum rigidity to the structure of the pneumatic controller (2).
It is important to highlight that, due to its construction and the materials used, the modular internal tank inspection system (1) of the invention is an intrinsically secure system, since the pneumatic controller (2), which enters into contact with the product stored in the tank (8), does not release any electrical energy and does not produce sparks, that might be caused by friction against the tank walls (8). In this way, the modular internal tank inspection system (1) can be used on tanks that store the most different types of liquid fuels, with no risk of explosion.
The elements that integrate the modular internal tank inspection system (1), the object of this invention, use materials, components, and fixtures known in the state of the art. Therefore, the components of the modular internal tank inspection system (1) may be fastened to each other using bolts, rivets, glue, soldering, or any other method of fastening known in the state of the art. The components of the pneumatic controller (2) may be constructed of an appropriate polymer material, such as polyurethane, commercial products such as viton (fluorinated polyethylene) and Teflon (fluorinated polypropylene), metal alloys or any material, with the mechanical characteristics and physico-chemical properties necessary for carried out their functions. It should be also highlighted that, for the manufacture and assembly of the pneumatic module (3), of the interface module (4), of the control module (5) and of the operation module (6), components used are known in the state of the art, such as valves, connections, printed circuit boards, microprocessors, converter boards, video monitors, keyboards, and [power] sources. However, the assembly now proposed constitutes a new and an innovative set.
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
